Hard to say what the reaction will be. People could shy away from pork which would lead to a supply glut in the pork market (bearish). On the other hand, if pork demand doesn't wane too much, but there is a campaign to dispose of infected pork inventory; there could be a supply squeeze accompanied by a rise in prices. Need to see what the geo-political reactions are going to be.

If considering equities, the small cap bios would be the place to look. These events rarely have any sinificant effect on large caps. Or IOW, there's usually more bang for the buck in a small cap reacting to some news.

Circadian's suggestion was dead on. You want to monitor the news and see what reaction, if any, there is to it.
